"What the hell?" I exclaimed. 

"Ye, expect this more often okay?" Jimin said while sitting down. 

"We're officers, not detectives." I said and sighed. 

"But this part of our job. Remember we are doing this for mom and dad. Okay?" he said. I nodded and heave a deep sigh. I looked at Seokjin who's really serious. 

"So, what does it really mean Jimin-ah." he looked at us. 

"Here, I'm done decoding it. This one's creepy." he said and sighed. 

"I will cut your throat and take your bones..." I whispered. My forehead creased. 

"The message is getting creepier. And I think it really talks about death." Seokjin said. 

"I know oppa. What's next?" I said. "I will cut your throat and take your bones... death... this is making me crazy as hell." I murmured. 

Night came and I changed my outfit into something comfortable. I wore black pants, a white sweater and sneakers. And braided my hair.

"Where are you guys going? Really in the middle of the night?" I heard Yuna said. I looked around and saw the both of them talking. I sighed and crossed my arms. 

"We need to go back to that abandoned place babe." my brother said.

"It's already late Jimin-ah." she said. I shook my head and smiled. 

"These two really," I whispered. "Yah! Give some respect here!" I shouted. They both look at me. I rolled my eyes and looked at Yuna. 

"We'll be back. Don't worry." I said and smiled at her. She sighed and nodded. 

"Take care you two!" she said. Jimin and I went out the house and saw Seokjin, Jungkook and Taehyung. I snorted the moment we went near them. 

"Where the hell are you guys going? Fashion show? Tss. We're going to get clues and investigate, not do some catwalk." I said and shook my head and decided to drive our car. Jimin oppa was sitting in the passenger's seat and the three of them are at the back. 

"Why didn't you wear your signature clothes Ye?" Seokjin started talking while driving. 

(ps. the picture above shows their clothes, don't mind yerin's outfit) 

"What do you mean?" I asked. 

"Miss black." Jungkook added and they laughed. 

"Haha funny. At least it's comfortable." I said and rolled my eyes. Later on, we arrived at our place. 

"Where did you find it?" I asked Seokjin. He lead the way and we followed him. 

"This place stinks." Taehyung said beside me. I rolled my eyes. 

"I told you to wear something comfortable." I scolded him. He blinked his eyes. 

"I'm sorry. I just want to look good." he said. I rolled my eyes. 

"There's no girls in here idiot." I said and shook my head and walked ahead. 

We arrived at the place and there were papers, everywhere.

"Okay, let's just clean this mess up and find something that can help us." I said and started roaming around. I heard Jimin sighed. 

"That's a lot." he murmured. 

We continued cleaning and I found two pieces of papers that has something identical like the other paper we have. 

"I found two." I said. 

"I found one." Taehyung said. 

"I can't find any." Jungkook said. I rolled my eyes for the nth time and shook my head. 

"That's because you were just sitting in there and eating. Psh." I said and shook my head. 

"We found one." Jimin said. I sat down on the chair for them to see what I've got. 

"More morse codes and two papers with binary codes." Taehyung said. 

"Decode it." I said and stood up. Taehyung took my place and he started writing it. 

On the first paper, there was, "-. .- ..- --. .... - -.-- / .--- ..- -. --. .-- --- -. .-.-.-" and on the second paper it was, "-. .- ..- --. .... - -.-- / .--- .. ... --- --- .-.-.-" 

"What does this mean?" I asked Taehyung. 

"Woah woah." he said. I looked at him. 

"What?" I asked. 

"This is actually creepy. It has names!" he exclaimed. 

"Huh?" Jungkook asked. 

"It says, Naughty Jungwon. Naughty Jisoo." I looked up to him and blinked. 

Wait!

"That's our parents names!" Jimin exclaimed. 

"The two of these means naughty Jungwon and naughty Jisoo. Which is your parents name." he said. "How about the binary Jimin-ah?" he asked. 

This one says,  01101001 01110011 00100000 01100011 01101111 01101101 01101001 01101110 01100111. And the other one is weird, dqg L'p derxw wr eorz.

"What the hell is this? This is giving me a fcking headache." Yerin exclaimed.

"Oh, this one is shifted alphabet code. Or the Caesar cipher. This one is easy." he says. I looked up to him. 

"What does it mean?" Jungkook asked eyeing the paper Taehyung was holding. 

"A Caesar cipher or Caesar code is a shift cipher, one of the most easy and most famous encryption systems. It uses the substitution of a letter by another one further in the alphabet." Taehyung explained. I looked at him, amazed. How does he know about these things?

He looks cool. 

"Tell us the meaning of this Taehyung-ah." Jimin said. 

"The meaning behind this is, and I'm about to blow. That's what it says." he said. We all nodded and made a circle. I sighed.

"Okay, so now we have. I will cut your throat and take your bones, death, and I'm about to blow and Naughty Jungwon and Naughty Jisoo." Jungkook said and I bit my lip. "Wait, what does this mean Jimin oppa?" I asked my brother. 

"It says, 'is coming.'" he said. I nodded, grabbed a pen and a paper. 

"Now we just have to arrange it." I said and tried to figure out what's message behind it. 

It took me 30 minutes to solve it but I can't. 

"Calm down Ye." Jimin said. 

"My head is aching because of this." I irritatingly said. 

"We just need to focus." Jungkook said. "Noona, how about you put the naughty words first?" he added. 

"Yeah, I should do that too." I said. 

Naughty Jungwon. Naughty Jisoo. I whispered. 

"Naught Jungwon. Naughty Jisoo. I will cut your throat and take your bones?" Taehyung interrupted. I looked at him and blinked. 

"Woah, Taehyung-ah, you got a point there. That can be the arrangement." Seokjin said. "Put it in there Ye." he said. 

I nodded and followed them. 

I stared at it and blinked. 

"Ah! I got it!" I exclaimed. 

"What?" 

"Naughty Jungwon. Naughty Jisoo. I will cut your throat and take your bones, death is coming and I'm about to blow." I said and looked at them. "That's the meaning behind those codes!" I said and looked at them.
